To all Iwhom may concern.'

Be it known that I, J osnrn PoLzI'N, a clti- Zen of the United States, `residing at Rock Island, in the county of Rock Island and the art to which it appertainsto make and use the same: l My invention has highly eflicient water heating device for ap- 1. plication to washing machines, bath tubs,

water tanks, registers, etc. p l

A further object is t0V so construct the device as to permit the use thereof for supporting and heating numerous kinds of containers or cooking utensils.

With the foregoing 'general Y objects inV view, the invention resides in the novel ea- Y tures of construction to be hereinafter fully described and claimed, the descrlptive matter being supplemented by the accompany ing drawings which form a part of this specification, and in which:

Figure 1 is a side elevation showing the application of the invention to a washing machine;

Fig. 2 is a bottom plan view of the heater with the burner and water circulating pipes detached;

Fig. 3 is a horizontal section on the plane ofthe line 3-3 of Fig. 1; and

Figs. 4 and 5 are vertical sections on the planes of the lines 4 4 and 5-5 respectively of Fig. 2.

In the drawings abov-e briefly described, the numeral 1 has reference to a fiat horizontal top plate which is preferably though y not necessarily of rectangular Jformation, the under side of said plate being provided with a pair of spaced parallel hollow ribs 2 and 3 which form therewith an inlet and an outlet conduit. Additional parallel ribs 4' are formed on thelower side of the plate 1 and form with said plate a plurality of branch conduits extending between the inlet and outlet conduits and communicating therewith. The several ribs are by preference cast integrally with the top plane l, butinsome types of the device, said ribs could well be stamped from sheet metal and brazed or otherwise secured in place. In either case, the several ribs will by' preference be V2 for its principal obje-ct to providea simple and inexpensive, yeta particular shape is not essential. Theconstruction described forms a plurality of parallel heat pockets 5 Vbetween the ribsl L1, which pockets are closed at their ends by the ribs 2 kand 3. This arrangement insures effectivev heatingof the several hollow ribsl so that the water circulating therethroughwillbe raised quickly to a high temperature.l

`One end o the rib 2, andthe other end of Vtl 1e"rib'3, are formed with openings in which inlet and return pipes 6' and 7 respectively are tapped, these pipes being connected to' the container ofthe water to be heated vand thus serving to support theentire heating device. 'f

The particular locationof the pipes, that is, at Adiagonally opposite corners of the plate 1, insures that the 'latter kshall not.A tilt.` It therefore forms an effective hot rplate for -supportingnumerous kinds of containers ,8 whereby the contents thereof maybe heated. v A burner 9 is locatedbeneath the ribs of the plate 1 and may be constructed to consume any kind offuel, such as gas, kerosene,

crude oil, alcohol, gasolene, etc. Burner 9 is provided with a horizontal supply pipe 1() K Speccation of LettersPatentV `,]-a,te11ied i shaped in transverse section although `rthis passing through an opening 11 in a vertical n arm 12 and clamped in said openin by a set screw or the like 13. Arm 12 pre erably depends fromthe rib 2, and if the entire device be made cfa casting as shown in theA drawings, said arm will beformed mtegrally with this rib.

In applying the improved heater, the two pipes l6 and 7 are connected with the container whose contents are to be heated, said pipes communicating with said container at comparatively low and high levels, respectively. The water thus enters the heating device through pipe 6 and after being heated, rises from said device through the pipe 7.k

Continuous circulation is maintained as long as the burner is in operation, with the result that the water will be heated in a short length of time. As above suggested, the` burner is applicable for a great number of uses, but for illustrative purposes, I have lshown the same applied to a common type of washing machine. Regardless of its application, however, the device will be highly efiicient, and due to its construction, will be a lconvenient means 0f heating the contentsy of utensils or the like by placing them on the plate 1 as indicated in Fig.v

of the advantages derived, the specificI construction shownand described consttuteek 1. On account Cji the preferred Yorlnof theiniproved heater, but I wish it understood that within the scope ol the invention as,claimed,,numerousv minor changes may be made without sacricing the principal advantages.

I claim:

1. A water heating device comprising-ay and outlet conduits, and a burner beneath said plateand ribs. v

2. ,A waterheater comprisinga top plate, a pair, of spaced hollow ,ribs on theunder side of said plate and formingtherewithan inlet and an outlet conduit each having means 4at one, end for connecting Aa circulating' -pipe thereto, additional hollow ribs on the yunder side of said'plate land forming therewith branch lconduitsy extending between and communicating `with y,said inlet yand outlet conduits, a vertical arm depending from one of said conduits and having anopening adjacent its lower end, a fuel `Gcpiessoi'thispatent may be obtained for ve cents each, by addressing the supply' pipe passing `through said opening, and a burner supported by said pipe and po- 4sitionedffor heating' the several conduits.

3. A water heating' device comprising a cast horizontal top plate of substantially rectangular configuration, a pair of hollow ribs castjintegrally with the under side of v,ribs at right angles to the others and` cast integ'rally` therewith and with the lower sldeofsaid top plate, said additional ribs communicating with said v,first named ribs,

-a vertical ,arm cast integrally with one of said flirst named ribs and depending therefrom, said arin having' adjacent its lower end an opening', a fuelsupply pipe passing throughy and secured in said opening, and a burner supported by said pipe yand positioned for heating the several ribs.

In testimonywhereof Iyhave hereunto set my hand in the presence of two subscribing,`

witnesses.
